IMPROVEMENT IN ENVELQPES. H

Specification forming part of Letters Patent N 0. 188,299, dated March13, 1877; application filed January 24, 1877.

To all whom it may concern:

Be it known that I, JOHN ELLIs MAR.- SHALL, of Buffalo, in the county ofErie and State of New York, have made certain Improvements in the Formand Construction of Safety-Envelopes, of which the following is aspecification My invention is intended for the use of express-companiesand corporations having occasion to transmit money and valuable papers,and its object is to supply an envelope protected with double folds ofpaper running along both sides and top, and rendered still more secureby a double gumming (inner and outer) of each of said sides and top, ashereinafter In the drawings, Figure 1 represents the envelope flat, asfirst out from the sheet. Fig. 2 is a plan with the bottom or lower flapfolded up into place. Fig. 3 is a plan with the bottom and one side flapfolded. Fig. 4 shows all the flaps folded except the top, the dottedlinewm indicating where the top or last told is to be made. Fig. 5 showsthe envelope folded and sealed, ready for transmisslon.

The construction and gumming or pasting together of the envelope may bemore particularly described as follows: A represents the inside of theface of the envelope, and a b c c the flaps of the same. The lower edgeI) of the flap b is first gummed and allowed to dry, like thesealing-flap of ordinary envelopesl The part below the dotted line a a('i. 6., theflap b) is next folded over and pasted to the body of theenvelope, along its edges 61 d, as shown in Fig. 2. Next, the two sideflaps c c are folded over along the dotted lines 0 0, Fig. l, and pastedfirmly to the body of the envelope. (See Fig. 4:.) The remaining top'fiap a is then gumnied along its entire length and left to dry, afterwhich it is creased along the dotted line 6 c, Fig. 1, and the envelopeis ready for use.

After the envelope receives its inclosure, the mucilage along the innerside of the edge I), Fig. 4, is moistened, and this edge gummed downupon the flap a, which is then, in turn, moistened and gnmmed down,folding over also the edge I), preparatory to the envelope being sealedwith wax at the junction of the four flaps, as shown in Fig. 5.

Reviewing the processes above described, it will be seen that we have anenvelope wherein the two sides and the top are all three protected theirentire length by a double fold of paper, and also still further securedby the double gumming described-first, the gumrning down of the threeedges 1) d d of the lower flap 1), Fig. 1, upon the inside of the flapsa, c, and 0, respectively, and, second, the

guinming down of these flaps themselves in the further construction andfinal closing of the envelope.

I an: acquainted with no envelope that combines so many elements ofsafety in so simple a manner. An GXPIGSS'GHVBlOPG in common use is madeby folding down the side flaps first, and bringing the top and bottomflaps together, so as to secure a double fold of paper along the top andbottom of the envelope; My envelope differs from this essentially, inthat the lower flap folds over first, and the side flaps and top downupon it, reversing the three edges of the lower flap in such manner asto secure double folds of paper across both ends and along the top ofthe envelope.

I claim A safety-envelope constructed with a flap, I), having its edgesoverlapping the flaps a and c, and its corners beveled or cutaway, toallow the flaps a 0 c and the overlapping edges of the flap b to befolded neatly when the envelope is closed, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
